Specification of Letters Patent.

Patented Apr. 2Q, 1915.

Application filed January 12, 1914. Serial No. 811,564.

To all whom it may concern Be it known that we, LOUIS BERGER and GEORGEA. HASSINGER, citizens of the United States, and residents of NewOrleans, in the parish of Orleans and State of Louisiana, have inventeda new and useful Improvement in Non-Refillable Bottles, of which thefollowing is a specification.

This invention relates to non-refillable bottles, and one of theprincipal objects thereof is to provide a stopper which may be fittedinto the neck of a bottle and which embodies means to permit permanentflow of the liquid from the bottle, but to prevent refilling of thesame.

Another object of the invention is to provide means for preventing theretraction of,

the stopper from the bottle neck after the former has once beenpositioned therein.

A further object is to provide a device of the classdescribed, whichwill be simple, durable, eflicient in operation, and comparativelyinexpensive to manufacture.

With these and other objects in view, which will become apparent as thedescription proceeds, the invention resides in the construction,combination and arrangement of parts hereinafter more fully describedand claimed, and illustrated in the accompanying drawing in which likecharacters of reference indicate like parts throughout the severalfigures, of which,

Figure 1 represents a vertical, sectional view taken through the neck ofa bottle, showing the device in position therein and showing theposition of the parts when the bottle is in upright position, Fig. 2represents a view similar to Fig. 1, showing the bottle as inverted,Fig. 3 represents a side elevational view of the stopper, removed fromthe bottle, Fig. 4; represents a horizontal sectional view on the line%l4 of Fig. 1, and, Fig. 5 represents a horizontal sectional View on theline 55 of Fig. 1.

Referring more particularly to the drawing, the numeral 5 represents thecylindrical neck of the bottle 6, and at 7 is shown a stopper which iscylindrical in shape, and Which is positioned within the bottle neck,below the upper end thereof. The stopper is provided in its lowerportion with a valve chamber 9, communicating at its upper end with theupper portion of the bottle neck through a restricted opening 10 formedby an annularbeading or flange 11 projecting inwardly from walls of thestopper in spaced relation with the upper end thereof.

The valve chamber 9 is substantially funnel-shaped, being of a greaterdiameter at its upper than at its lower end, and has seated therein asubstantially egg-shaped valve 12, adapted, when the bottle is inupright position as shown in Fig. 1, to drop into the lower end ofchamber 9 to close the same and to prevent filling of the bottle, aswill be readily understood. The upper or larger end of the valve isprovided with a plurality of spaced radially extending, substantiallytriangularly shaped lugs 8 whose upper edges fall in a common place atright angles to the longitudinal axis of the valve, and whose purpose isto prevent seating of the larger end of the valve in the opening 10 whenthe bottle is entirely inverted, so that the liquid contained in thebottle may pass around-the valve through the opening.

Positioned above the restricted opening 10 is a substantiallyfrusto-conical disk 13 of a diameter less than the diameter of the upperend of the stopper, but slightly greater than the diameter of therestricted opening, and connected by means of spaced arms 1& with thewalls of the stopper, so that the contents of the bottle, when the sameis inverted, may flow around the disk 13, between arms 14. The disk isadapted to co-act with the flange or beading 11, to prevent theinsertion of a wire or other instrument for opening of the valve 12 orfor holding the same in open position when the bottle is returned to anupright from an inverted position, and the flange 11 also acts as a stopto limit the outward movement of valve 12 from its seated position. Nearthe lower end of the stopper, the same is provided with an annulargroove 15, on its outer surface, which co-acts with a reduced lower endportion 16 of the stopper for forming an annular flange or collar 17,occurring between the reduced portion and groove 15, and a plurality ofsprings 18 are secured in spaced relation in any desired manner at theirlower ends to collar 17 and at their upper ends are bent outwardly, theninwardly so that they may be housed within the groove 15, when forcedtoward the stopper incident to the insertion of the latter within thebottle neck, the normal tendency of the springs, however, acting toproject the upper ends thereof outwardly from the groove. 7

The springs are adapted to engage an annular shoulder 19, formed in thebottle neck 5, by means of an outwardly enlarged annular portion 6 ofthe bottle neck, to prevent retraction of the stopper, once the same hasbeen positioned in the bottle neck, said annular enlarged portion at itslower end as at where it joins the lower portion 21 of the bottle neck,being of a diameter somewhat less than the diameter of the upper portionof the bottle neck, so that the reduced portion 16 of the stopper snuglyfits in the lower portion of the neck, and when the stopper is inposition the flange or collar 17 overhangs the portion 20 and is adaptedto rest against a compression ring 22, seated thereon, so that therewill be no rattling or movement of the stopper after the same has beenput in place, as will be readily understood.

In order to readily position the valve 12 within the valve chamber 9, aportion of the lower end of the stopper has been made of a separatesemi-tubular piece A, which forms substantially one-half of the wall ofthe valve chamber and which extends from just below flange 11 to thebottom end of the stopper, and which is held in place by the action ofthe spring 18, carried by that section and by the fact that it isembraced by the walls of the upper and lower portions of the bottleneck, as will be readily understood, it being obvious that the valve 12is positioned in the valve chamber, and the sections A fitted into placebefore the stopper is placed in position within the neck of the bottle.It will be understood that the bottle is first filled, and the stopperthen inserted into the neck of the bottle, and subsequently a cork Bplaced within the bottle neck above the stopper, the frusto-conical disk13 acting as a limit to the inward movement of the cork.

When the contents of the bottle are to be removed, the cork should betaken out and the bottle partially inverted, so that the valve 12 willdrop from its seated position into the enlarged upper end of the valvechamber 9, resting on the lowermost surface of the chamber when thebottle is in the position shown in Fig. 2, the movement of the opening10 and out around the disk 13,

through the upper end of the bottle neck. The bottle may be entirelyinverted in pouring; its contents, or it may be partially inverted, asshown, however in either case the lugs 8 will prevent choking of thepassage 10 by the valve. After the stopper has once been positioned inthe neck of the bottle it will be impossible to remove the stopperwithout breaking the neck, since the springs 18 cannot be retracted fromtheir engagement with shoulder 19, and since the stopper may not beforced into the body of the bottle for the reason that the inwardmovement of the stopper is limited by the flange 17.

Although we have described the preferred embodiment of our invention, wemay desire to make such changes in the construction, combination andarrangement of parts as do not depart from the spirit of the inventionand the scope of the appended claim.

We claim:

The combination with a bottle having a neck, of a stopper adapted to fitinto said bottle neck, means to prevent retraction of said stopper fromsaid neck, said stopper having a substantially funnel-shaped chambercommunicating with the interior of the bottle, said chambercommunicating by a restricted opening having convex walls with the upperend of the bottle neck, a substantially egg-shaped valve adapted to seatin the smaller end of the chamber when the bottle is in uprightposition, and adapted to unseat when the bottle is inverted, afrustoconical disk positioned adjacent the restricted opening and beingof a diameter greater than the diameter of the opening, arms connectingsaid disk with thewalls of the stopper, and a plurality of triangularlyshaped radially disposed lugs on the larger endof the valve to preventseating of the valve in the restricted opening.
